DRAFT-EQUALIZEIR.

SPECIFICATION forming part of Letters Patent No. 399,766, dated March 19, 1889.

Application filed November 26, 1888. Serial No. 291,839. (No model.)

T 0 aZZ whom it may concern:

Be it known that I, JONAS P. MCDOWELL, of Foote, in the county of Iowa and State of Iowa, have invented a new and Improved Draft-Equalizer, of which the following is a full, clear, and exact description.

My invention relates to an improvement in draft-equalizers, and has for its object to provide a device especially adapted for attach ment to the tongues of harvesters, which will be of simple and durable construction, and in connection with which three or more horses may be employed.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification, in which the figure represents a perspective view of the equalizer attached to a pole or tongue.

In carrying out the inventioinA represents the pole or tongue of a harvester, upon the left-hand side of which, at the inner end, an essentially triangular iron, B, is bolted, the forward or straight member whereof is provided with three or more apertures, 1). Upon the right-hand side of the tongue, a distance in advance of the triangular iron 13, a horizontal arm, (I, is pivoted by means of a single bolt passing through the arm and tongue, and the said arm, which projects outward from the tongue at a right angle, is limited in its lateral movements by a brace or stayplate, G.

Upon the outer end of the arm 0 an evener, D, is centrally pivoted, and a connecting-rod, I), is employed to unite the evener and its supporting-arm with the triangular iron B. This connecting-rod and the triangular iron are adapted to receive the entire draft.

The outer end of the connecting-rod is forked, as illustrated at (I, one member of which forked end is retained in position by engagement with the top and the other menr her with the bottom of the bolt, pivoting the evener upon the supporting-arm.

The inner end of the connecting-rod D is slotted, as at d, to receive the forward or straigl'it member of the triangular iron, and

provided with a vertical aperture.

The 0011- necting-rod is secured to the triangular iron B, or what may be designated a bracket, by a pin, (Z passing through the aperture in the rod and one of the apertures in the bracket.

At each end of the evener, upon the upper side of the same, a doubletree, E, is pivoted, the same being preferably effected by causing a clevis or clip, 6, to embrace the evener and doubletrees, and passing a bolt through the horizontal member of the clips, the evener, and doubletrees. By this arrangement of the doubletrees it will be observed that one singletree, c, is upon the left of the tongue near the grain, and three singletrees, (2 are located at the right of the tongue. To the "rear of the evener, when parallel with the supportii'ig-arm C, a stop-block or bracket, F, is vertically secured to the tongue, adapted to limit the rearward movement of the left ex,- tremityof the evener and prevent the doubletree at that end from interfering with the binder. The stop F also serves to hold the evener at a right angle with the tongue when turning corners.

The adjustment of the connecting-bar is provided to give the advantage of leverage to the weaker animal when placed either at the right or left of the tongue, the adjustment in the drawing being in favor of the animal at the left of the tongue.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a tongue and an arm projecting horizontally at a right angle to the same, of anevener centrally pivoted upon the outer end of the arm, a doubletree pivoted to said evener at the extremities, and a stop secured to the. tongue limiting the inward movement of one extremity of the evener,substantially as shown and described.

2. The combination, with a tongue, an arm projecting horizontally outward at a right angle from the .right side of the tongue, and an evener centrally pivoted upon the free end of the arm, of a doubletreepivoted upon said evener at each extremity, clips embracing the evener and doubletrees, and a stop attached to the tongue limiting the rearward movement of the left-hand extremity of the evener, all combined for operation substantially as shown and described.

3. The combination, with a tongue, a horizontal apertu red bracket secured at one side near the inner end, and a horizontal arm pivoted upon the tongue extending outward from the opposite side in advance of the bracket, of an evener pivoted upon the outer end of the arm, a doubletree pivoted upon the extremities of the evener, a stop secured to the tongue at the rear of the arm, and an adjustable connecting-rod uniting the evener, the arm, and the bracket, all combined for operation substantially as shown and described.

4:. The combination, with a tongue, a horizontal apertured bracket secured to the left side of the tongue near the rear end, a pivoted arm extending at a right angle from the sta e right-hand side of the tongue in advance of the bracket, and a strap limiting the movement of said arm, of an evener centrally pivoted upon the free end of the arm, a doubletree pivoted upon each extremity of the evener, a stop secured upon the tongue limiting the rearward movement of the left eX- tremity of the evener, a connecting-bar having forked extremities uniting the arm and evener with the bracket, and a detachable pin passing through one forked end of the connecting-rod and one aperture in the bracket, all combined for operation substantially as shown and described.
